The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in theatmosphere, but we now know that that is a rather minor constituent of theatmosphere.

The atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere are composed of crystals of methane.

NADPH builds up in the STROMA of the chloroplasts during electron transport. In chloroplasts, NADP+ is reduced by the ferredoxin-NADP+ reductase.

Nicotinamide adenine dinucleotide phosphate (NADPH) is the reduced electron form of NADP+.

The NADPH coenzyme is generated during the last step of the electron transport chain of the light-dependent reactions of photosynthesis.

NADPH is used by plant cells as an electron donor in different reactions associated with dehydrogenase and reductase enzymes.
